When Nazi Germany began its occupation of Denmark in April 1940, Greenland suddenly found itself cut off from its colonial power and thrust into the centre of North Atlantic wartime strategy. The US took control of Greenland temporarily, establishing bases and defence perimeters there to prevent Germany from using the island.
More than 80 years later, Donald Trump invoked that moment at the World Economic Forum in Davos. In his speech on January 21, the US president claimed his country “gave Greenland back” to Denmark after the second world war. This history, Trump implied, still gives the US a claim to Greenland today.
